Abstract
An increasingly popular way to interact with machines is to simply talk to them. However, there is often a trade-off between ease of use and system complexity. Thus, the main objective of this project is to design and
implement a voice control car using RF technology for wireless data transmission it is capable of accurately identifying a single sound while remaining simple and fast. For this purpose, an algorithm like Linear Predictive Coding is prototyped and tested using MATLAB. On the hardware side we interfaced RF module with Microcontroller, speech recognition is performed using PC, Microcontroller then convert bits from
serial port to message and transmit it, receiving side RF respond and order
car to move, Speech is a complex and non stationary signal produced as a result of several and complex transformations, sound signal changes a lot due to many factors so it is not possible to have 100% accurate result, Result of our system are more than 70 percent, The system as though looks
astonishing for lay man but we are hoping that this could be a small step for
helping blind and disable people to solve their everyday problems.
